Very little. Open-source code of IvanHoe 999946h was modified to compile under Windows in the MP mode. Some code was borrowed from Ivanhoe.x64.VE.f. SLAB_MEMORY and SEE_VALUE features were enabled. For SLAB_MEMORY, a small code change was needed to get it to work. For SEE_VALUE, trivial code changes and parameter tuning were performed to make the feature useful. Minor bug fixes in material_value.c and matval_explain.c. Split depth values tuned in IH_SMP.h. RobboBases were turned off (a trivial thing to do once I couldn't quickly get them to work). My main concern was that, even though IvanHoe is open-source, for many compiles it's not obvious which code they are compiled from. The question arose, "What is the air-speed velocity of an unladen swallow?" (c) Monty Python. Preliminarily it looks like it's pretty close to that of IvanHoe 46ei x64 SSE4.2, and that's good news to me.

Hi folks ... I do not know if I happened to me ... but Ivanhoe 9.46h 01a35, is working only with 1cpu, the more I put 6cpus ... he does not carry all ... just works ... I 1cpu using windows 10 (amd platform, fritz 14 gui) ... a hug
